A recent addition to what could be the next tsunami of copyright suits, Jim Peterik of 1982 Survivor fame is contemplating getting the rights back for the gloriously awesome song “Eye of the Tiger”. Source.
Termination rights are covered in Title 17. Long story short, if you licensed or assigned your copyright to someone after Jan. 1, 1978, you (or your heirs) can terminate that license or assignment after 35 years (provided you gave proper notice). Do not pass go, do not collect $200. The basis for termination has been around for awhile, but no one really cared about it because…well….there seemed to be a tendency to go all Scarlet O’Hara and say “Well, I won’t think about it now. I’ll think about it tomorrow”. Fiddle dee dee! Welcome to tomorrow.
